It is a naphthoic acid derivative, which can be prepared by the reaction of 2-hydroxy-3-naphthoic acid with formaldehyde. In pharmacology, the ester form of pamoic acid (pamoate ion) can be used as a counter ion of a drug compound to increase the solubility of the drug in water. The presence of multiple oxygen atoms enables significant hydrogen bonding to occur, where the hydrogen bonds facilitate the dissolution of compounds in water. It is also called as water Pamoic acid disodium salt; 4,4'-Methylenebis(3-hydroxy-2-naphthoic acid) disodium salt; Embronic acid sodium salt.
